Surface Plate Dealer In Ahmedabad, Surface plates provide a precision reference surface for layout, checking, machining, and gaging work. Two types of surface plates can be used: a granite surface plate or a cast iron surface plate. Granite is considered the best material for surface plates because its properties (e.g., surface hardness, low thermal expansion, no rust or corrosion, little warping, longer wear life) result in very accurate, stable, and precise surfaces.
